I can find nowhere that we call unregister ide-dma for modules.
All I can suggest to you is to not compile ide-dma into the modules.
This is something that I will look into, but is not of the highest
priority to date.
Gadi is out of the IDE-driver business to the best that I can tell.
He is overloaded with other tasks to complete.
Thus, I have offered to look over and potentially maintain the driver,
since I live and die by ide-drivers support...........
Cheers,
Andre
